# What is Hy?

Hy (a.k.a., Hylang) is a dialect of the Lisp programming language designed to interoperate with Python by translating expressions into Python's abstract syntax tree (AST). Similar to Clojure's mapping of s-expressions onto the JVM, Hy is meant to operate as a transparent Lisp front end to Python's abstract syntax. Hy also allows for Python libraries (including the standard library) to be imported and accessed alongside Hy code with a compilation step, converting the data structure of both into Python's AST.

# How to use this image

## Create a `Dockerfile` in your Hy project

	FROM hylang:0.10
	COPY . /usr/src/myapp
	WORKDIR /usr/src/myapp
	CMD [ "hy", "./your-daemon-or-script.hy" ]

You can then build and run the Docker image:

	docker build -t my-hylang-app
	docker run -it --rm --name my-running-app my-hylang-app

## Run a single Hy script

For many simple, single file projects, you may find it inconvenient to write a complete `Dockerfile`. In such cases, you can run a Hy script by using the Hy Docker image directly:

	docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp hylang:0.10 hy your-daemon-or-script.hy
